The install got to around 20% and now I'm stuck on a black screen with 'Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key'. Follow the guidelines below to do this: Restart your computer and when it comes on, continuously press the required key to enter your computer's BIOS screen the keys vary for different computers and they include Del, F2, Esc, etc.
